Strange behavior when using sophos connect vpn.

hi there,
of 80 users who use "Sophos connect", we see behavior in about 10 which we currently do not understand.

there are two locations, locations A and B, both locations are connected by an IPSec tunnel, V17.5 MR11.
Most users connect to location "B" with the "Sophos connect". The Exchange Server is located in location "A".

the following behavior can now be seen in the 10 affected users.
if they have connected to location "B", no TSL / SSL to Exchange is possible, neither Outlook nor OWA website works (ping works).
if these affected users use the SSL VPN client on the same FW (same fw rules), everything works again.
there is also no problem if the affected user connects to location "A" in which the Exchange Server is located.

The question is, why do these 10 users have problems with TLS / SSL when they use "Sophos connect" and are connected to location "B"?
A ticket has been open here for 4 weeks, but without a solution.

Does anyone know of such problems, thanks for any help.
